IPC: G11B7/00
Filed: 1979-09-20
Abstract: PURPOSE:To make it possible to improve resolution of still pictures, by not recording the sound signal on the disc but extending the side band of the picture signal for recording of the still picture in case that still pictures and dynamic pictures are recorded selectively onto the disc-shaped recording medium. CONSTITUTION:The video signal input from terminal F is separated into luminance components and color components by separating circuit 101, and luminance components are led to FM circuit 102, and the FM signal is led to dynamic picture/still picture mode change-over switch 103a. This switch 103a switches the signal to HPF 104 for dynamic picture which permits region (f) or more to pass through and the HPF for still picture which permits region (g) or more to pass through. That is, in the still picture recording time, the sound signal is not recorded on the disc recording medium, and the side band region of the picture signal is extended to (g); and in the dynamic picture recording the reproducing time, sound signal components are converted to frequency regions (a) and (b) between color signal components (c) converted to a low band and FM luminance signal components (d) and are superposed onto the FM luminance signal and the color signal and are recorded. As a result, resolution of still pictures can be improved.

Title: Device for controlling door
Inventor: TAKAHASHI HIDEAKI
IPC: B66B13/26
Filed: 1990-05-14
Abstract: PURPOSE:To avoid increase of torque of a door driving motor in the case where a passenger is caught in doors, and also to change a door speed quickly in a normal state by controlling driving torque of the door driving motor so that the motor can output the driving torque without time lag so as to correspond to a detected value of a rotational speed of the motor, which depends upon a moving speed of the door. CONSTITUTION:If a passenger has been caught in doors while the doors are closing at a constant speed, the doors will stop, and then an electric motor will reduce its rotational speed, and will stop finally. At that time, as the rotational speed of the motor 5 decreases, torque command from a torque commanding circuit 10 increases, on the contrary, a speed value 6a sensed by a speed sensor 6 decreases much more than the increase of the torque command. Accordingly, sum of the torque command 10a and the sensed speed value 6a decreases. Consequently, when the rotational speed of the motor 5 decreases, voltage command 11a from a voltage commanding circuit 11 decreases. For this reason, voltage to be supplied to the motor 5 also decreases. Thus, even if a passenger has been caught in the doors, it is possible to prevent a state dangerous to the passenger by suppressing sudden increase of closing force of the doors.

Abstract: PURPOSE:To enable the direct power reception from a commercial power system by connecting a variable resistor in parallel with electric facilities when the electric facilities, which receive power supply from the power system, cause sharp power fluctuation. CONSTITUTION:When the electric facilities receiving power supply from a power system 12 produce the power fluctuation in the reductive detection being sharp enough to fluctuate the voltage, etc., of this power system 12, switches 28a-28c are actuated to connect variable resistors 26a-26c in parallel with the electric facilities, and the amounts of power fluctuation are consumed once with these variable resistors 26a-26c.

Title: Method and device for die casting
Inventor: GOSHIMA TOSHIBUMI
IPC: B22D31/00
Filed: 1989-05-16
Abstract: PURPOSE:To allow taking out of a casting at prescribed timing before supercooling by previously divided providing a die for pouring to allow mounting and detaching thereof and detaching the above-mentioned die for pouring from a die for casting while the molten metal in a sprue part is in a half-solidified state after pouring. CONSTITUTION:The die 16 for pouring is mounted to a notched step part 14a of the die 14 for casting by operating a robot 18 for attaching and detaching the die for pouring. The robot 18 is retreated upon lapse of the prescribed time after the molten metal is packed into the cavity of the die 14 for casting from the sprue part 16b and solidifies. The molten metal solidified between an outflow port 16c of the sprue part 16b and a receiving port 14c is cut by cutting blades 16d, 14d to detach the die 16 for pouring from the die 14 for casting. Since the molten metal near the central part is not yet solidified in the sprue part 16b, the unsolidified molten metal falls from the sprue part 16b and is recovered into a recovering vessel. The die 14 for casting is opened and the casting is taken out when the casting is put into the prescribed solidified state by the detachment of the above-mentioned die 16.

Title: Integrated circuit
Inventor: SUGANUMA TOSHIO
IPC: H03K19/00
Filed: 1989-05-16
Abstract: PURPOSE:To prevent fluctuation of the resistance due to fluctuation of a power voltage by providing a MOS transistor(TR) acting as a pulldown resistor and 1st and 2nd resistors connected in series between a power supply and grounding device, and applying a voltage divided by the resistors as a back gate bias voltage of the MOS TR. CONSTITUTION:When a power voltage VDD gets higher, a gate-source voltage VGS of a MOS TR 6 is increased and acts in a direction of decreased on- resistance, and a back gate bias voltage is increased in response to the ratio of the resistances of 1st and 2nd resistors 7, 8. Thus, the threshold voltage of the MOS TR 6 is increased and the ON-resistance is changed increasingly. Thus, the ratio of the 1st and 2nd resistors 7, 8 is set in response to the characteristic of the MOS TR 6 to prevent the fluctuation of the ON-resistance of the MOS TR 6 as a whole. Thus, the fluctuation of the resistance due to the fluctuation of the power voltage is prevented when the pulldown resistor is constituted by the MOS TR.

Title: Sample-and-hold circuit

IPC: G11C27/02
Filed: 1983-07-07
Abstract: PURPOSE:To reduce an offset voltage by compensating unbalance of currents of a current mirror circuit being an active load of a sample-and-hold circuit. CONSTITUTION:When a base potential of a transistor (TR) 28 is higher than the base potential of a TR29, collector currents Ic23, Ic24 of TRs 23, 24 are increased by the characteristic of the current mirror circuit and an excess collector current Ic24 charges a capacitor 27. Thus, the base potential of the TR29 is increased in response to a sample voltage and the potential of the base of the TR28 and that of the TR29 are equal. The unbalanced current flowing to a drive stage of the current mirror circuit is compensated by collector currents Ic28, Ic29 of the TRs 28, 29 through the connecting constitution of the TR29 because of the effect of the base current of the TRs 23, 24 and an offset voltage DELTAV' is reduced.
